Get player sets

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

ReadOnlyHint=true already signals a safe read operation; the description adds behavioral specifics beyond that: ordering ('most recent first'), format normalization ('same normalized set form as get_event_sets'), and enrichment ('plus the event and tournament each set belongs to'). This gives the agent expectations for output shape and ordering without contradicting annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences with no filler. The core purpose is front-loaded, and the comparison to get_event_sets and mention of included fields are stated efficiently. Every phrase earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read-only tool with full schema coverage and no output schema, the description covers all essential aspects: what it returns, ordering, format reference, and filter capability. It leaves nothing an agent needs to call it correctly, relying on the schema for parameter specifics and the annotations for safety.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description adds minimal value beyond schema: it references filtering by state (e.g., COMPLETED) which maps to the 'state' parameter, but does not elaborate on syntax or defaults. The schema already handles parameter documentation adequately.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Get'), a specific resource ('a player's recent sets across tournaments'), and key characteristics: most recent first, normalized set form, and inclusion of event/tournament. It clearly distinguishes from get_event_sets by comparing the form, making its purpose unmistakable.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It implies usage context by referencing get_event_sets and specifying that sets are across tournaments (rather than within a single event). However, it does not explicitly state when to prefer this over get_event_sets or other alternatives. The guidance is clear enough for an agent to infer intent, but lacks explicit 'when not to use' directions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
